Turn Signal/Multifunction Lever
Turn and Lane Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow located on the
instrument panel cluster
will flash in the direction
of the turn or lane change.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it is released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off.Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned
-out signal bulb.
Other drivers won't see the turn signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and check for burned
-out
bulbs if the arrow fails to work when signaling a turn.
Headlamp High/Low Beam
When the low-beam headlamps are on, push the turn
signal lever away from you to change the headlamps to
high beam.
This light on the
instrument panel cluster
will be on, indicating
high
-beam usage.
Pull the turn signal lever toward you to return to
low
-beam headlamps.

2-37 Flash-To-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
Pull the turn signal lever toward you briefly to
flash

If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high
-beam
headlamps will turn on. They'll stay on as long as
you hold the lever there. Release the lever to turn
them off.

If the headlamps are on low beam, they will remain
active and the high beam will also illuminate until
you release the lever.
Windshield Wipers

after the windshield wipers have been in use for
approximately six seconds.

2-44
To operate the wiper-activated headlamps, the Twilight
Sentinel
must be on. If the wiper-activated headlamps
are on and the ignition key is turned to ACC, the
wiper
-activated headlamps will continue. When you
turn the key to OFF or ACC, the wiper

a HEADLAMPS SUGGESTED message will be
displayed on the Driver's Information Center (DIC).
Lamps On Reminder
You will hear a warning chime if you open the driver's
door while leaving the lamps on and the exterior lamps
control is activated. An exception to this is when you're
using Twilight Sentinel or if the ignition is on.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make the high
-beam headlamps
come on at reduced brightness when:

The ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).
When DRL are on, only your high
-beam headlamps
(at reduced brightness) will be on. No other exterior
lamps such as the parking lamps, taillamps, etc. will be
on when the DRL are being used. Your instrument
panel won't be lit up either.

2-45
When the Twilight Sentinel
switch is on and it's dark
enough outside, the high
-beam headlamps (at reduced
intensity) will turn off and normal low
-beam headlamp
operation will occur. When the Twilight Sentinel switch
is on and it's bright enough outside, the regular lamps
will go off, and the high
-beam headlamps at reduced
brightness will take over.
If it's dark outside and the Twilight Sentinel control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver's Information Center (DIC). This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are still
illuminated. This message indicates that it has become
dark enough outside to require the headlamps and/or
other exterior lamps. Turning on the Twilight Sentinel
or the headlamps will deactivate the DRL and remove
the HEADLAMPS SUGGESTED message. If the
parking lamps or the fog lamps were turned on instead,
the DRL will still deactivate and the HEADLAMPS
SUGGESTED message will continue to be displayed.
To idle your vehicle with the DRL off, turn off the
Twilight Sentinel and shift the transaxle into PARK (P).
Placing your vehicle in PARK (P) disables the DRL.
The DRL will stay off until you shift out of PARK (P).To drive your vehicle with the DRL off, turn off the
Twilight Sentinel and manually turn on the parking
lamps or fog lamps (if equipped).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps (STS Only)
Use the fog lamps for better vision in foggy or misty
conditions. When you push the fog lamp button located
next to the exterior lamps control, a small indicator light
in the fog lamp button and the LIGHTS ON and fog
lamp indicator lights on the instrument panel cluster will
tell you that the fog lamps and the parking lamps are on.
Pushing the fog lamp button again will turn them off.
If you turn on the high
-beam headlamps, the fog lamps
will turn off. They'll turn back on again when you
change to low
-beam headlamps. You can use the fog
lamp button to turn the fog lamps on or off when the
parking lamps or headlamps are on.
When the Twilight Sentinel

is on and the fog lamps are
turned on, the fog lamps, headlamps and parking lamps
will remain on.

2-46 Cornering Lamps
The cornering lamps come on when the headlamps
or parking lamps are on and you signal a turn.
They provide more light for cornering.
Twilight Sentinel

This control is located
below the exterior
lamps control knob.
It automatically turns
the lamps on and off
by sensing how dark
it is outside.To operate the Twilight Sentinel, leave the exterior
lamps control knob off and move the TWILIGHT lever
to any position but OFF.
If you move the lever all the way to the right, the lamps
will remain on for approximately three minutes after the
ignition has been turned to OFF or ACC. If you move
the lever so it is just on, the lamps will go off quickly
when you turn the ignition out of ON. You can adjust
the delay time from only a few seconds to three minutes.
If it's dark enough outside and Twilight Sentinel is
turned off, a HEADLAMPS SUGGESTED message
will display on the Driver's Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended (it has become dark
enough outside to require the headlamps and/or other
exterior lamps). Turning on the Twilight Sentinel,
the headlamps or the fog lamps will remove the
HEADLAMPS SUGGESTED message.

2-47
Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinel is located on the driver's side
of the front defogger grille. If you cover the sensor,
it will read ªdarkº and the lamps will come on.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately
ten minutes after the ignition is turned to OFF. This
protects against draining the battery in case you have
accidentally left the headlamps or parking lamps on.
The battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamps control knob to
turn the lamps back on. To delay the lamps from
turning off, see ªTwilight Sentinelº in the Index.

2-49 Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the driver's door switches
and to the ignition key when a door is opened or if you
press the Remote Keyless Entry (RKE) transmitter
unlock button. The illuminated entry system works with
the light sensor and it must be dark outside in order
for the courtesy lamps or backlighting to turn on. The
courtesy lamps turn off approximately 25 seconds after
the last door is closed or after the ignition key is turned
to RUN or if the RKE transmitter lock button is pressed.
The courtesy lamps turn off approximately 40 seconds
after the doors are unlocked with the RKE transmitter
if no door is opened.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the parking lamps are
on. This feature works with the light sensor and is fully
automatic. When the light sensor reads darkness outside,
the instrument panel lights can be adjusted by following
the steps under ªInstrument Panel Intensity/Brightness
Control.º Backlighting to the instrument panel will
also turn on.
Reading Lamps
The reading lamps are located in the roof. These lamps
and the interior courtesy lamps come on when any door
is opened and it is dark outside. The rear lamps come on
when a rear door is opened. Press the button near the
lamps to turn them on and off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle
at a higher revolutions per minute (rpm) setting than
normal to make sure the battery charges. High electrical
loads may occur when several of the following are on:
headlamps, high beams, fog lamps, rear window
defogger, high blower fan, heated seats and engine
cooling fans.
